Sumo Direct Drill
Optimum seed placement with minimal soil disturbance are the major benefits of the DD, a disc-based drill designed for zero-till crop establishment as part of integrated conservation agriculture, benefiting the environment and increasing margins.
Possible savings that can be achieved by adopting a DD system are a 70% cost saving/ha over conventional tillage and a 55% saving over minimal tillage, with labour savings/ha of 80% and 55%, respectively. The minimal soil disturbance element of the DD technique provides additional benefits, including improved soil structure, easier grass weed control, moisture retention in the rooting zone, reduced erosion, improvements in drainage and the ability to integrate cover crops into the rotation.
The DD is designed and engineered with these objectives in mind, to give optimum seed placement in a wide range of conditions, and incorporates a number of innovative designs; slim line single disc openers, adjustable disc down force, in-house designed ORGA metering system, ruggedness and simplicity.
Seeding units on the DD are mounted on spring pressurized parallelograms on mounted models, trailed models are hydraulically pressurized, which allows for contour following and down force adjustment. A single 450mm disc set at an angle cuts through the soil and opens up a trench which seed is placed into. A spiked wheel then follows which breaks the trench wall and covers the seed with soil and firms the seeding area. Row spacing is 200mm and has a drilling depth range of 12mm-100mm with manual adjustment.
